FIBERFcovERED METALLIC TUBING, A mavron FOR SILK srnn'ronmo AND DRYING- To all whom it may concern Be it, known that I, JACOB Knocr'r, a citizen of the United States, residing at, 230 Clinton street, in the city of Paterson, in the county of Passaic and State of New J ersey, have invented certain new and useful Improvements in Fiber-Covered Metallic Tubing, a Device for Silk Stretching and Drying Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in means for hanging or suspending skeins of silk in an apparatus for stretching and drying silk, such as the apparatus shown in -my U. S. Letters-Patent No. 969,960, patented September 13, 1910. In drying and stretching machines of that character, it has been the custom to use sticks or metal bars or tubing, which pass through the skeins, to all of which there are objections; namely,

sticks are not strong enough for the strain,

and the silk is apt/to catch on all of said skein holding means as the metal ones are apt to get wet and rust.

The ob'ects of my improvement are, first, to provi e for hanging or suspending the silkskeins a means which will be strong, light and durable, that will have a hard, smooth surface not ,apt to catch or enga e and entangle in any Way with the si k thread; second, to produce a means, for hanging or suspending silk in machines of the character above stated, that may be extended and shortened to meet the demands or requirements of the number of skeins of silk that are to be stretched and dried; third to produce in a machine for stretching and drying skeins of silk, a means for hanging and suspending the silk, consistin of a vulcanized fiber-covered metallic tu ing; and fourth, to provide sleeves of vulcanized fiber, telescopic tubes in said sleeves for supporting skeins of silk passed around said sleeves, and means within said tubes for operating and guiding the inner tube and to revent it from turning. I attain these ob ects by the mechanism illustrated in the accompanying drawings, in which Figure 1' is a section of metal tubing partly covered by the fiber covering or sleeve; Fi 2 an end view of the same; Fig. 3 is an '11 ustration in longitudinal section Specification of Letters Patent.

of the telescopic sections of adjustable fibercovered metallic tubes and means for ,operating the same; Fig. 4 is ing at the operating end of device; Fig. 5 is an end view showing the telescoping portions and gui e rods looking at the other end, and Fig." 6 is a crank or key for turning thethreaded rod to operate the telescopic sections to lengthen or shorten the same.

Similar letters refer to similar throughout the several views.

an end view lookparts The fiber sleeve or covering F is vulcan- I ized, hard, dense, closely resembling horn in texture, and has a very smooth surface and is made of vegetable fiben. The silk therefore cannot catch or be entangled by the smooth surface of the fiber sleeve or coveri'ng and both the metal tube and its fiber covering contributes to the strength of my device, which may be called a skein-holding device for silk drying and stretching machines.

The tubing M is covered by the sleeve of fiber F and is meant totake the place of the rods described in my above mentioned patent and the skeins of silk are hung around my fiber covered tubing in a chain or series in the same manner as ent.

Sometimes it happens that there are more skeir:- of silk to be stretched and dried than can be accommodated around the rods or described in said patfiber-covered tubing on one machine, but are nevertheless not enough to fill the rods or fiber-covered tubing of another machine, hence, I provide two fiber-covered tubes adapted to telescope or )ass one within the other and which may e operated by the handle -fto extend or withdraw the in ner tube from or into the outer tubing, which tubes are shown in longitudinal sec tion in Fig. 3. To prevent the inner tube from turning, I provide guide rods -e-e which aresecurcd in the fixed nut -c and which pass through the collar -din the inner tube. ,The fixed nut cin the outer tube is interiorly threaded and the operating screw a passes through said nut, and according to the direction in which said screw -11 is turned, it forces the inner tube/out from or draws it into the outer tube. As shownin Fig. 3 the screw bolt Ig* asses loosely through the fixed c01- lar in the inner tube and is screwed into the inner end of the screw a. The fined nut -cinthe-outer tube and the .5. fixed collar in the inner tube, and the guide rods eesecured in thenut c and passing slidably through the fixed collar in the inner tube, comprise a'reinfor-cement or strengthening element to the telescopic portions of the inner and outer tubes.

. My tubes are preferably constructed of metal and while the invention has been described with particular reference to the details of construction, it is not to be considered as limited thereto, as many changes may be made Withoutdeparting from the scope of the following claims.

What I claim and stretching machines, comprising a vul-- canized fiber-covered tubing.

2. A skein-holding device for silk drying and stretching machines, comprising in com- -bination a metallic tube and a covering for the same, consisting of a sleeve of vulcanized vegetable fiber. I

3. A skein-holding device for silk drying a nd stretching machines, comprising in com- 1. A skein-holding device for silk drying justing the length of the skein-holder.

6. In a skein-holder for silk drying and stretching machines, a tube of any suitable substance, provided with a sleeve or covering of vegetable fiber, vulcanized to produce a hard, dense surface, closely resembling horn in texture and presenting a very smooth surface, substantially as set forth. In testimony whereof I aflix my signature in presence of two witnesses.
